Rapid assembly and disassembly lamp shade structure

ABSTRACT

A rapid assembly and disassembly lamp shade structure comprised of a top ring, a bottom ring, and frame members propped between the top ring and the bottom ring. The bottom ring has aligned with the top ring support rod positions and extending from the center to its circumference slide rods and, furthermore, coupling rings capable of traveling back and forth along the slide rods are ensleeved onto the slide rods. Each coupling ring has projecting upward a hinge tab with a through-hole formed in it, the bottom ends of the paired brace rods of the frame members are punched into a flat shape and, furthermore, the fastening sections have an insertion hole formed in the center, thereby providing for riveted conjoinment of the frame member fastening sections to the coupling ring hinge tabs. Capable of traveling reciprocally along the slide rods, the coupling rings maintain the top ring and the bottom ring in a reinforced open state or are folded down such that the top and bottom rings are brought against each other in a closed state. As such, the invention herein achieves rapid assembly and disassembly and, furthermore, a reduction in material storage area that effectively lowers shipping costs.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1 and FIG. 2, the structural arrangement of thepresent invention, the invention herein is comprised of a top ring 1 atthe uppermost end of the lamp shade, a bottom ring 2 of largercircumference than the top ring 1, and frame members 3 propped betweenthe top ring 1 and the bottom ring 2, of which:

The said top ring 1 has support rods 11 extending from the center to thecircumference and, furthermore, the support rods 11 are aligned with theframe members 3 at the circumferential edge of the top ring 1 and aninclosing space 111 is formed by upward bending that provides forsituating the top ends of the frame members 3 against the bottom edge ofthe inclosing space 111.

The said bottom ring 2 has aligned with the top ring 1 support rod 11positions and extending from the center to its circumference slide rods21 and, furthermore, before the slide rods 21 are installed, couplingrings 22 capable of traveling back and forth are first sleeved ontotheir rod bodies; each coupling ring 22 has projecting upward a hingetab 221 and, furthermore, a through-hole 222 is formed in each hinge tab221 to provide for conjoinment to the frame member 3 fastening sections32.

The said frame members 3 have their top ends against the bottom edge ofthe inclosing spaces 111, each said frame member 3 consisting of a pairof brace rods 31, the separation of which is gradually reduced from atop rod 33 such that the bottom ends merge and become flush, with thebottom ends of the rod bodies continuously punch molded into flat-shapedfastening sections 32 and, furthermore, an insertion hole 321 is formedin the center of the fastening sections 32; each fastening section 32 isaligned with a coupling ring 22 hinge tab 22 and a rivet P is insertedinto each through-hole 22 and insertion hole 321 to conjoin the framemembers 3 to the bottom ring 2.

Referring to FIG. 2 and FIG. 3, the coupling rings 22 are first sleevedonto the slide rods 21 of the bottom ring 2; of the frame member 3 bracerod 31 pairs that are gradually reduced in separation from the top rod33 until the bottom ends become flush, the bottom ends are punched intoflat-shaped fastening sections 32; furthermore, the fastening sections32 at the bottom section of the frame members 3 are aligned with thecoupling ring 22 hinge tabs 22 and conjoined by the rivet P to providefor an appropriate turning angle of the frame members 3 on the couplingrings 22 and, furthermore, the coupling rings 22 capable of travelingreciprocally along the slide rods 21; when the coupling rings 22 aresituated against the center portion of the bottom ring 2, the bottomring 2 and the top ring 1 are maintained at a maximum distance apart andthe frame members 3 are engaged into position between the top ring 1 andthe bottom ring 2, thereby resulting a reinforced open state (as shownin FIG. 2); when folding is desired, the coupling rings 22 are movedtowards the outer side of the bottom ring 2 such that the frame members3 are released from engagement with the top ring 1, thereby providingfor folding the top ring 1 down against the bottom ring 2 into a closedstate (as shown in FIG. 3) and, as such, when packaged in cartons, thelamp shade of the present invention occupies the smallest physicalassembly space to facilitate ease of assembly and disassembly and,furthermore, the resulting minimized storage area effectively reducesshipping costs.

Referring to FIG. 4, the drawing of another embodiment of the inventionherein, the said frame members 3 have their top ends situated againstthe bottom edge of the inclosing space 111, each said frame member 3consisting of a single brace rod 31′ extending downward from the centerof the top rod 33 and the bottom ends are continuously punch molded intoflat-shaped fastening sections 32, with an insertion hole 321 is formedin the center of the fastening sections 32; the coupling rings 22 aresleeved onto the slide rods 21 of the bottom ring 2, each coupling ring22 has projecting upward two hinge tabs 221′ in a parallel arrangementand, furthermore, a through-hole 222 is formed in both of the two hingetabs 221′ to provide for aligning the frame member 3 fastening sections32 between the two hinge tabs 221″ and a rivet P is inserted into eachthrough-hole 222 and insertion hole 321 to conjoin the frame members 3to the bottom ring 2; since the coupling rings 22 are capable oftraveling back and forth on the slide rods 21, the top ring 1 can befolded down against the bottom ring 2 into a closed state.

Referring to FIG. 5, after the assembly of the said lamp shade frameworkis completed, the exterior periphery of the top ring 1 and the bottomring 2 are covered with a fabric material lamp shade 4, wherein theexterior fabric surface layer 41 of the said lamp shade 4 is firsttightly fitted onto the outer periphery of the frame members 3; theinterior fabric surface layer 42 is then placed along the inner sides ofthe frame members 3 and, furthermore, an adhesive fastening tape 43 isrespectively applied over the appropriate portions of the interior andthe exterior fabric surface layers 41 and 42, the frame members 3 areenveloped within such that the frame members 3 remain unexposed due tothe ensconcing structural arrangement constituted by the interior andthe exterior fabric surface layers 41 and 42, while also effectivelyachieving an attractive appearance; in addition, when the framework isfolded, the lamp shade 4 collapses along with it to achieve a reductionin material storage area and thereby effectively lowers shipping costs.

Referring to FIG. 6, the drawing of the invention herein as installed onthe lamp pipe 5, the said lamp pipe 5 has at its top end an terminalfixture 51 of a stepped arrangement and, furthermore, the said terminalfixture 51 is secured in the middle ring 2A at the center of the bottomring 2 to support the lamp shade 4.
